justin bieber lipsync fail and vomiting on stage

Lip-syncing is a common occurrence, particularly in the entertainment industry. It's often considered a regular practice, and although many artists manage to pull it off without detection, there have been instances where some have been unmistakably caught in the act.
Take Justin Bieber, for example. He not only faced being caught lip-syncing but also experienced an unfortunate incident of vomiting on stage. It's certainly an example of an unfavorable day in his career. Feel free to observe for yourself.
